What you can work out here

Most of these started life as a tool I wanted for myself, so they lean towards the sums that actually come up in ordinary life — money, time and health, with the odd unit conversion thrown in. A few of the ones people reach for most:

💼 Salary & take-home pay — what actually lands in your account after tax, National Insurance and pension, for the UK or any US state.
🏡 Mortgage repayments — the monthly figure, the total interest, and a full year-by-year breakdown.
🏷️ Stamp duty — the SDLT on any property price in England and Northern Ireland, worked out band by band.
📈 Compound interest — how a pot grows over the years once the interest starts earning interest of its own.
⚖️ BMI & body fat — where you sit on the standard health scales, in metric or imperial.
🔥 Daily calories — your BMR and TDEE, with sensible targets for holding, losing or gaining weight.
📅 Days between dates — the exact gap in days, weeks and months, leap years handled for you.
🎂 Your exact age — down to the day, along with a live countdown to the next birthday.
📈 World market hours — which stock exchanges are open right now, on a live day-and-night map.
🔄 Unit conversions — length, weight, temperature and the rest, with a dedicated height converter.
